YacReaderLibraryServer dockerized

Yeah it was root until I changed it.

These are the entire logs:

A duplicate repeats once and then I get this repeating a few times:

This line is suspicious, you should see your library there. Instead there is nothing, which explains the errors further down in the log. Try to add the library and if you are successfull, post the log here so we can continue troubleshooting.

Yeah, as @selmf said you don't have any library, I think that you lost your server settings after updating it, maybe? So just add the library or libraries again and everything should work as expected.

Pretty sure this is exactly what happened to jefftr66. I commonly have to do this after a docker update.

Deleted everything and reinstalled. Now after creating library nothing shows up.

I notice the second series shows the Library but 1st doesn't

I think I see it now. There are two problems:

1. The config file of the library server is located in the container, so you need to add the libraries every time you update the docker
2. The container integrates libraries via Docker's volume mechanism and expects comics to be located on the container under /comics

Naturally, if your library is not correctly mounted your docker container will not be able to update or create it.

You can find instructions how to correctly mount and use the volume at jcshumpert's git for the docker:

@jefftr66, @jcshumpert and other docker users: I have created an issue for this on our Github. It would be great if you could give some input on your user experience and troubles so we can cut down these problems in the long run.

github.com/YACReader/yacreader/issues/259

The current diagnostics and checks are simply not enough to easily solve problems like this.

If I run across any issues I'll be sure to chime in. I remember when I was first learning Docker there were some hurdles I ran into, but can't remember any of the specifics. Now that I've had mine up and running for so long I (thankfully) haven't run into any issues.

I think some of the confusion may have been with the formatting of my readme. I think it was unclear to those new to Docker that the example commands have variables surrounded by <> that need to be updated to fit their preference. I just updated my readme to provide an example so hopefully that will be clearer for those just starting out with Docker.

Hi! I'm new to docker and raspian in general. I keep getting this error when I use your pull command, do you have any insight?

Error response from daemon: manifest for jcshumpert/yacreaderlibrary-server-docker-raspberrypi:latest not found: manifest unknown: manifest unknown


This is the pull command I'm using: docker pull jcshumpert/yacreaderlibrary-server-docker-raspberrypi

The issue is docker tags are case-sensitive. Docker auto-tags the most recent build as 'Latest'. I'm not sure why it is auto-appending the 'latest' tag when you run the pull command. Maybe you have an older version of docker?

Out of curiosity, try updating your pi by running these commands:
After each of those complete do a reboot with:
And then try the docker pull command again. If that doesn't work, you can try this docker pull command to explicitly tell it to grab the 'Latest' tag.
